YES 4 TON IS GREATER THAN 7,000
Answer: 1 < x < 25
<u>Step-by-step explanation:</u>
The sum of two sides must be GREATER than the third side.
a + b > c a + c > b b + c > a
12 + 13 > x 12 + x > 13 13 + x > 12
25 > x x > 1 x > -1
x < 25 1 < x
Length cannot be negative so disregard x > -1
We are left with 1 < x and x < 25
1 < x < 25

The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.
X⁴-14x²+45=0
(x²) ²-14x²+45=0
let y=x²
y²-14y+45=0
(y-9) (y-5) =0
y=9 or y=5
x²=9 or x²=5
x=±3 or x=±√5
